Prysmian said it would be responsible for the design, manufacture, supply and testing of 175km of inter-array cabling at the site, which is due online by 2021.

Cables will be produced at the company's Pikkala site in Finland.

In March, the cable firm announced a €170 million investment in a new cable-laying vessel, due to enter operation by Q2 2020. It will have deep-water cable-laying capability, increased loading and rotating platforms.

MHI Vestas, announced as the preferred supplier for the project, is set to deliver 77 V164 9.5MW turbines to the site.
